WASHINGTON — The White House has released a photo showing that the couple who crashed President Barack Obama's first state dinner actually shook hands and talked to him — contradicting earlier Secret Service claims that Obama was never endangered by the security breach.

As the White House was disclosing that the couple, Michaele and Tareq Salahi, met Obama in the receiving line, a "deeply concerned and embarrassed" Secret Service on Friday acknowledged that its officers never checked whether the two were on the guest list before letting them onto the White House grounds.

The White House released a photo showing the Salahis in the receiving line in the Blue Room with Obama and Indian Prime Minister Manmohan Singh, in whose honor the dinner was held. Obama and reality TV hopeful Michaele Salahi are smiling as she grasps his right hand with both of hers and her husband looks on. Singh is standing to Obama's left.

The Secret Service had said previously that the president was not in danger because the couple — like others at the dinner — had gone through magnetometers. But in light of their close proximity to the president, no such claim was made Friday.

"This incident compromised the safety and security of the president and undermined our confidence in the protection we expect of the Secret Service," said Rep. Edolphus Towns, chairman of the House Oversight and Government Reform Committee.

'Embarrassed'Disturbed by the agency's failure "to follow basic security procedures," the New York Democrat said in a statement Saturday he wants a review of Secret Service practices and has asked for a briefing next week.

The Salahis were not on the guest list and should have been barred from entering last Tuesday's dinner on the White House South Lawn for the prime minister of India, said Secret Service Director Mark Sullivan.

Sullivan said the agency that protects the president is "deeply concerned and embarrassed" that procedures were not followed.

"As our investigation continues, appropriate measures have been taken to ensure this is not repeated," Sullivan said in a written statement.

"The preliminary findings of our internal investigation have determined established protocols were not followed at an initial checkpoint, verifying that two individuals were on the guest list," Sullivan said. "Although these individuals went through magnetometers and other levels of screening, they should have been prohibited from entering the event entirely. That failing is ours."

Agency spokesmen declined comment Saturday on reports that agents had visited the Salahis' vineyard in Hume, Virginia, in search of the couple. Voice mail messages left Saturday at two separate telephone numbers for the Oasis Winery, south of Washington, were not immediately returned.

Secret Service spokesman Jim Mackin said officers at the checkpoint had a clipboard with names of the invited guests. Even though the Salahis names weren't on it, they were allowed to proceed. The officers should have called someone on the White House staff or Secret Service personnel before allowing them past the checkpoint, Mackin said.

Earlier, Mackin said the Secret Service may pursue a criminal investigation of the Salahis.

Sullivan said it wasn't good enough that his agency screened more than 1.2 million visitors last year to the White House complex and protected more than 10,000 sites for the president, vice president and others.

It is unclear what the couple told officers at the checkpoint that allowed them to go through the security screening. Federal law makes it a crime to knowingly and willfully falsify statements on matters within the federal government's jurisdiction.

"As this moves closer to a criminal investigation there's less that we can say," Mackin said. "We're not leaving any option off the table at this point."

The Salahis lawyer, Paul Gardner, posted a comment on their Facebook page saying, "My clients were cleared by the White House, to be there." He said more information would be forthcoming. Several messages left at Gardner's law firm on Friday and Saturday were not returned.

Bravo Media has confirmed that Michaele Salahi is being considered as a participant in the upcoming "The Real Housewives of D.C." program and on the day of the dinner was being filmed by Half Yard Productions, the producer of the program.
